Got a tissue handy? Lea Michele's full cover of Bob Dylan's "Make You Feel My Love," which will be featured in Glee's Oct. 10 tribute to her late boyfriend, Cory Monteith, surfaced online on Sunday, Oct. 6, and -- not surprisingly -- it's a heartbreaker.

The emotional ballad (which has also been covered by Billy Joel and Adele, among others) is easily the 27-year-old actress' most soulful and moving performance yet. Fans got a sneak peek of the song on Oct. 4, when Fox released a short preview clip of the episode, but you can hear her full rendition now.

"Almost everything in that episode is from the first take of every performance, because the actors and the crew had a really hard time shooting it," Murphy explained. "I've never seen a crew where you can't continue shooting because they left the room sobbing."

He continued: "It was very hard, and I struggled even working on it, because you're seeing what they felt about not just Finn [Hudson, Monteith's character], but Cory. So I think it's amazing performances across the board, and everybody went into it with a lot of love."

Murphy also noted that the experience was "very rough" for Michele, who was Monteith's girlfriend both on and offscreen. "People are still not over it," he said of the 31-year-old actor's tragic July 13 death of heroin and alcohol toxicity. "It's still very, very difficult."
